Abstract

Animal colostrum and milk contain complex mixtures of oligosaccharides, which have species-specific profiles. Milk oligosaccharides have various types of structure related to the core structures of glycolipids and N- and O-glycans of glycoproteins and provide a good library to examine the binding of oligosaccharides to various lectins. Recently, we reported a capillary affinity electrophoresis (CAE) method for analyzing the interactions between lectins and complex mixtures of N-linked oligosaccharides prepared from serum glycoproteins [K. Nakajima, Y. Oda, M. Kinoshita, K. Kakehi, J. Proteome Res. 2 (2003) 81-88]. The present paper reports the interactions between 24 milk oligosaccharides and six lectins (PA-I, RCA120, SBA, WGA, UEA-I, and AAL) analyzed using CAE. Based on the resulting data, we constructed a library that enables us to determine nonreducing terminal monosaccharides, such as Gal, GalNAc, GlcNAc, and Fuc, and to differentiate Gal- or Fuc-linked isomers, such as lacto-N-tetraose, lacto-N-neotetraose, and lacto-N-fucopentaose II and III. In addition, using the library, we show that a combination of the lectins can characterize the neutral oligosaccharides derived from bovine colostrum.
